    ¿Cuántos frascos de perfume de 20 mililítros cada uno pueden llenarse con 2,5 litros de dicho perfume?

    • 47 frascos

    • 125 frascos

    • 75 frascos

    • 325 frascos

    Correct Answer
    A. 125 frascos
    Explanation
    To find the number of 20 milliliter perfume bottles that can be filled with 2.5 liters of perfume, we need to convert liters to milliliters. Since there are 1000 milliliters in 1 liter, 2.5 liters is equal to 2500 milliliters. Now, we divide 2500 milliliters by 20 milliliters (the capacity of each bottle) to find the number of bottles that can be filled. 2500/20 = 125. Therefore, 125 bottles can be filled with 2.5 liters of perfume.

    • 5,55

    • Ninguna de las anteriores es correcta

    Correct Answer
    A. 5,23
    Explanation
    The correct answer is 5,23 because it is the only option that is a valid number. The other options, 5,33 and 5,55, are not correct because they contain an extra digit after the decimal point, which makes them invalid numbers. The option "Ninguna de las anteriores es correcta" means "None of the above is correct" and does not provide a valid answer. Therefore, 5,23 is the only correct option.

    En una clase de 36 alumnos, 1/3 han elegido como optativa el idioma francés y 1/6 el alemán. ¿Cuántos alumnos estudian idiomas?

    • 18 alumnos

    • 12 alumnos

    • 6 alumnos

    • Toda la clase estudia algún idioma

    Correct Answer
    A. 18 alumnos
    Explanation
    In a class of 36 students, 1/3 of them have chosen French as an elective and 1/6 have chosen German. To find out how many students study languages, we need to add the fractions together. 1/3 + 1/6 = 2/6 + 1/6 = 3/6 = 1/2. Therefore, half of the class, which is 18 students, study languages.

    El kilo de merluza está a 11,20 €. Si una merluza pesa 1,450 €, ¿cuánto costará?

    • 15,3 €

    • 16, 20 €

    • 16,24 €

    • 10, 55 €

    Correct Answer
    A. 16,24 €
    Explanation
    The cost of 1 kilo of hake is 11.20 euros. If a hake weighs 1.450 kilos, the cost can be calculated by multiplying the weight by the cost per kilo. Therefore, the cost of the hake would be 1.450 x 11.20 = 16.24 euros.

    Una persona gasta en alimentación 1/3 de lo que gana; en ropa 1/4 de lo que gana y en otros gastos emplea 1/6 de su salario. Ahorra 300 € al mes. ¿Cuánto gana cada mes?

    • 1200 €

    • 1000 €

    • 1500 €

    • Ninguna de las anteriores es correcta

    Correct Answer
    A. 1200 €
    Explanation
    The person earns 1200 euros per month. This can be calculated by adding up the amounts spent on food, clothing, other expenses, and savings. Since the person spends 1/3 of their salary on food, 1/4 on clothing, and 1/6 on other expenses, the total amount spent on these three categories is 1/3 + 1/4 + 1/6 = 13/12 of their salary. This means that the person saves 1 - 13/12 = 1/12 of their salary. Since the person saves 300 euros per month, their salary is 300 * 12 = 3600 euros per year. Dividing this by 12 gives a monthly salary of 3600 / 12 = 300 euros. Therefore, the person earns 1200 euros per month.

    • Ninguna de las anteriores es correcta

    Correct Answer
    A. -254/35
    Explanation
    The given answer is -254/35. This can be obtained by subtracting 234/35 from 254/35. When we subtract the numerators, we get -20, and the denominator remains the same. Therefore, the correct answer is -254/35.
